Aim of this paper is to present and discuss a case of a delayed cerebellar parenchymal hemorrhage developing after L/P shunt placement with a NPH patient. A hypertensive patient admitted to our clinic with a diagnosis of NPH. The patient was placed a pressure adjustable L/P shunt without any surgical complication. He was discharged with an uneventful period. The patient was admitted to the emergency clinic of our hospital with a 1.5 × 1.5 cm diameter hematoma at the left cerebellar hemisphere on 2 days after his discharge. CSF drainage by an L/P shunt can generate intracerebellar hemorrhages especially in hypertensive patients.

Meningioma is one of the most common tumors in the spinal cord. Extradural and en-plaque variety of meningioma occur less frequently. A 47-year-old woman is presented with radiculopathy signs. Magnetic resonance imaging revealed a lesion from C6 through T3 vertebral levels compressing the cord both anteriorly and posteriorly. Subtotally excision was performed and histopathologic signs showed transitional type of meningioma (WHO Grade 1). Post operatively, she had good neurological recovery. Intraoperative findings point out that the en-plaque meningioma was pure extradural. Twelve cases of pure extradural en-plaque meningioma have been reported in the literature. Besides, to the best our knowledge coexistence of "en plaque" spinal epidural meningioma with meningiomas in cranial cavity has not been reported. Complete resection is mandatory to prevent recurrence. Moreover, it is considerably difficult to remove the parts of tumor over anterior of the dura without complication.

Non-traumatic middle meningeal artery aneurysm and rupture resulting in intracranial haemorrhage is rare. In the present case, a 73-year-old man was admitted to hospital with a history of a minor head trauma. A CT scan of the head revealed a 2×2 cm intraparenchymal haematoma without significant mass effect in the left temporal lobe. The cerebral angiogram revealed a middle meningeal artery aneurysm. Intracerebral haematoma due to extracranial aneurysm is extremely rare, but should be considered when the history is suspicious and cranial CT is non-contributory.

AbstractÖz Ventriculoperitonal shunt dysfunction can be a displeasing result after management of hydrocephalus. Proksimal tip malfunction of the system is rarely seen compared with distal catheter. Here we report a 6-month-old infant who was treated with ventriculoperitonal shunt system after the diagnosis of hydrocephalus at birth and presented with shunt dysfunction 6 months after the operation.Ventriküloperitonal şant bozukluğu, hidrosefali yönetimi sonrasının istenmeyen bir sonucu olabilir. Sistemin proksimal uç bozukluğu, distal katetere kıyasla nadiren görülür. Burada doğumda hidrosefali teşhisi konulduktan sonra ventriküloperitonal şant sistem tedavisi almış fakat operasyodan 6 ay sonra şant disfonksiyonu gelişen 6 aylık bir yenidoğanın durumu sunulmuştur.
